Introduction: Laparoscopic partial nephrectomy has emerged as a standard of care for small renal masses. Nevertheless, there remains concern over the potential for irreversible insult to the kidney as a result of exposure to warm ischemia. We aim to investigate the utility of selective segmental arterial clamping as a means to reduce the potential for ischemic damage to a solitary kidney during laparoscopic partial nephrectomy utilizing a porcine model.

Background And Purpose: Laparoscopic retroperitoneal lymph node dissection (L-RPLND) is emerging as a viable alternative to traditional open retroperitoneal lymph node dissection (O-RPLND). Despite numerous reports confirming clinical oncologic equivalency between the two approaches, however, concerns still remain over the adequacy of laparoscopic dissection. We therefore sought to compare the completeness of dissection between O-RPLND and L-RPLND in a porcine model.

Objective: To evaluate the precision of cryoprobe targeting with a surface template, an in situ template (on the target organ), or a combined approach.

Materials And Methods: Fourteen participants placed five 17 G cryoprobes into porcine kidneys in a laparoscopic trainer using a surface template (group 1), an in situ template (group 2) or a combination of the two templates (group 3). The distance from the ideal probe placement was measured both on the anterior and posterior aspect of the kidney.
